How to use python programming for high-performance website construction?
[Guide] As a python programmer, you can not only use python technology to provide us with more convenience and achieve more computer skills development, but also website development and build high-performance websites. The frameworks commonly used to build websites using python are Django, Tornado, web py, web2py, CherryPy, Flask, Bottle, Quixote, etc. So how do you use python programming to build high-performance websites? Let’s learn more about the relevant frameworks.
1、nginx
nginx is a high-performance HTTP and direction proxy server, as well as an IMAP/POP3/SMTP server. Nginx is a lightweight web server, it is developed in c, the entire server is only a few M. Moreover, it occupies less memory and has strong concurrency. For example, Baidu, JD, Sina, Netease, Tencent, and Taobao all use nginx.
2、tornado
Tornado is also an open source server. The most obvious difference between tornado and mainstream frameworks such as Django is that it is a non-blocking server and the speed is quite fast. Tornado can handle thousands of connections per second, so tornado is An ideal framework for real-time web services, if combined with nignx, it can handle more connections. However, tornado has a disadvantage. There are relatively few third-party libraries, and many things need to be configured by yourself, but tornado is still relatively flexible and can be used in combination with other frameworks. Tornado does not support ORM operation. In the next article, I will introduce how to combine tornado, Django and nignx together to build a website. Let's compare with a picture below. Why should I choose tornado+nginx? The purpose of using Django is to facilitate the operation of the database.
3、Django
Django is a web application framework that develops source code and is written in python. Using the MVC framework, those who develop websites should know MVC, models, views, and controllers. This is a bit like the spring framework of java. The core components of Django are, the object-relational mapping of the model is created, that is, the table in the database is mapped to the class. When operating the database, you do not need to write SQL statements to directly manipulate the object to complete the operation on the table. When using the Django framework, you only need to define it first. The good class can then complete automatic data table creation with two commands, similar to hibernate's ORM, first-class URL design, designer-friendly template language, and caching system. The disadvantage is that Django does not support asynchrony, so it is still more suitable for small projects with low pressure, and cannot handle high concurrency. It's not a problem to learn Django and find a job.
The above is the method of using python programming to build high-performance websites. Of course, learning is endless, and learning a skill is a lifelong benefit. Therefore, as long as you are willing to learn hard, it is never too late to start. If you are engaged in python programming Thoughts, then hurry up and learn, and I wish everyone success!
